A man charged in an alleged plot to detonate pressure-cooker bombs at the legislature in Victoria on Canada Day last year has now been charged with a count of assault while in custody.

It’s unclear exactly what John Stuart Nuttall did that led up to the alleged assault incident on Dec. 2, 2013.

BC Corrections confirmed “an incident between inmates took place” at the Surrey Pretrial Services Centre,” but provided no further specifics.

“BC Corrections’ number one priority is to maintain a safe and secure environment — and to this end, BC Corrections reports alleged assaults within its correctional centres to local police agencies and co-operates with investigators,” it said in a statement.
